This 'invention relates to improvements in pulverizers.

object of the invention is to provide a pulverigier adapted to be attachedto a ,f tractor and which is especially desigzlnedA 'to be attached to a tractor known in the trade as the Fordson, and to provide means whercbythe discs or blades of the pulverizer may be rotated ,by the tractor, so as to eiliciently and thoroughly pulverize the ground over which the pulverizer passes.

A further object of the invention is to provide a pulverizer adapted to be attached to a tractor andto provide means Altor raising and lowering the pulverizing blades so that Y the depth `which the blades penetrate vthe ground may be varied. v

' A still further object ottheinvent-ion is to provide an improved pulveriaing device whereby the blades oi' `the pulver-ineimay be readily applied or detached from the pulf verizer. l

AW'ith the vioiegoing and other objects in view which will be made maniiiest inthe following detailed description and pointed out in the appended claim,re'lference is hadto the accompanying drawings for an illustrative ei'nbodiment ot' the invention, wherein:

Figure 1 is a rear elevation oit the pulver- "'f'" rizer as applied to a tractor;

Fig. Q is a side elevation showing' a portion` ot .the tractor to which `the pulveiizer has been applied, parts otthe ,pulxf'erizer be ing shown in section; v y

Fig. 3 vis a horizontal section taken stantially on the'line 3-3 ojl' Fig. 2;

Fig. l 'is a vertical section taken tially on the line et of Fig. 3;

Fig. 5 is a vertical section through a porsubstau Referring to the accompanying drawings wherein similar reference characters designate similar parts throughout, the tractor is shown as having rear drive wheels and l1,

which are mounted upon an axle 19 disposed within an axle housing 19. Upon the suitable i housin rear oft `the body or the frame of the tractor,

ythere is disposed anattachment v1li adaptedto attach a draw bar to thetractor". The partictilar tractor desoribedis provided with a adapted to receive a 'suitable mechanism whereby a lpower take-,oliQ for the tractor is provided. Usually a 'pulley attachment is adapted to be `niounted upon the housing 15 so as to bedrivenby the' side drive for oper atingvarious `farm machinery and the like.

In mounting 'thel'pulveiizer upon the ti'actolr,` a brace 1G has its center rigidly secured uponthe draw bar attachment 14 and hasits ends `,bent so as`lto` present a verticalv su'i'ft'ace,as indicated-at1'( The outerY ends ot the brace 'H16 are rounded, asindicated''at 18, and receive the ends ot brackets 19. The brackets 19 'entend yttorwa .rd ly` troni the brace [16 beneatlrthe axlehousing 1B, and a clamp `2l() is pivoted to the forward end ot each bracket 19, as at 21. The clamp 2O 'extends over vthe top ofthe axle housing 13 and'has itsv rearward end lfastened Ito the body 0f the bracketV 19 as'b'y a' bolt and nut 22. Adjacent the endsl ot the Vbrace 1G there 'are mounted boxes 223 which form guidewmeans for the Ypulvcrizer.' Members 2li' arev disposed within the boxes and aievei'tically slidablc'therein. These members are in the Vtornifof'racks, as indicated Q5, and have theiitlower ends slotted, as indicated at'QG. Bearing `blocks 27 are disposed within the lslots 2G of eachfol'lthe inenib'ers'ld and are fslidable therein, although they j are urged downwardly by iiieans oi2 sprin{ ;s 28. Ad ]a`c`ent the bottoni oi each oi' thefslots are arranged rockers 29 which have pins 30 piv- "otallv mounted inthe sides ot the members 24, wlii l"tleline'tlie slots 26.

A shat Slis ]ourn-.\`ledn1n the bearing blocks 2'? and extends transversely across the tractcijat the rear thereof. ddh-is shaft has .its center portion squared, as'indicated at SQfalngd `is adapted to receive clamping disc 'The clamping vdiscs 33r are held against rotation 'upon'the shaft ,31 `because of the dared portion 32, and 'upontheopposed aces of each pair or clampingdiscs there are Aarranged grooves 234i Betweeneaclipair of clamping" discs 33 ther-eis arranged a`disc or blade, generally designated at 35. The discs or blades 85 are formed of two complementary halves 36 and 37, although each disc may be made of more segments it so desired. Each haltl is semi-circular in form and has e, vindicated at'l, which is and 35b extend toward each other.

teeth 38 formed upon its periphery. VAdjacent the inner edge of each haltl there is formed a bead 39 adapted to occupy the groove 34 in one of the clamping discs 33 so as to prevent the halves from slipping out from between the clamping discs When the clamping discs are forced together. Lugs 40 are struck out from the body of each of the halves 36 and 37 and in the preferred form of construction, these lugs, when the halves of the discs are mounted, are so arranged as to extend toward each other from adjacent discs. Upon each half there `are two lugs 40, one beingstruck out toward one side of the disc and the other lug being struck out from the opposite side ot' the disc. The blades or discs 35 when assembled upon the shaft 3l, as indicated at 35, 35b and 35C, are so arranged that the lugs 40 upon the blaldle's ie other lug upon the halfof the disc 351 which is struck out in the opposite direction is opposite a corresponding lug upon the blade vor disc 35, as indicated in dotted lines upon Fig. 5. When the halves 36 and 37 of each of the blades or discs 35 have been placed between their respective clamping dises 33, a wedge ring 41 is'claniped between a pair of clamping discs, as shown in Fig. 5. This wedge ringis adapted to urge all o the clamping discs 33 upon the shaft 31 toward each other and thus clamp the halves or sections of the blades 35, preventing their removal.

Adjacent one end of the shaft 31 there is mounted a suitable housing 42, within which is disposed a worm wheel 43 rigidly keyed upon the shaft 31. A worm 44 meshes with the worm wheel 43 and is mounted upon a drive rod 45. The drive rod 45 is connected by means of a universal joint 46 to an extensible drive rod 47 having an extension joint 48. The opposite end of the extensible drive rod 47 has mounted thereon a beveled gear which meshes with a beveled gear driven by the side drive mechanism Within the housing l5. Both of these beveled gears are mounted upon suitable bearings within the housing 49. In this manner, as the tractor is driven, the side drive mechanism may be employed which will rotate the extensible drive rod 47 While the tractor is moving and in this manner drive the shaft 31, causing rotation of the blades35 and thus thoroughly pulverize the ground. If the discs 35 should strike a hardspot in the ground, the shaft 31 may rise against the action of the coil spring 28, and if one sideonly of the shatt31 is lifted,

for driving it.

the opposite side within its bearing block may pivot upon the rocker 29.

As a means for vertically adjusting the members 24 and, consequently, the shaft 31, Iprovide a housing indicated at 50 within which is disposed a gear 51 which meshes with the rack 25. The gear 51 is mounted upon a spindle 52 which extends transversely across the tractor between each of the housings 50. Upon one side of the tractor, preferably upon the right side, the housinvr 50 has an extension indicated at 53, in which there is mounted a pinion 54 which meshes with the gear 51. The pinion 54 is mounted upon a spindle 55 carrying a crank 56. In the handle 57 of the crank 56 there is slidable a pin 58 which operates a lever 59 upon which is mounted a pin 60 adapted to engage any oi a number of apertures formed in the side ot' the housing extension 53. In this manner by rotating the crank 56, the pinion 54 will rotate the gear 51. As the gear upon the 'right side of the tractor is rigidly mounted upon the spindle 52, the corresponding gear 5l upon the opposite side of the tractor, which is also mounted upon the spindle 52, will be caused to rotate with it. In this manner both ot' the men'ibers 24 may be simultaneously lifted within their boxes 23 and vertically adjust the shaft 31,. i

From the above it is seen that I have providedan improvement adapted to be readily attached to a Fordson tractor whereby the pulverizing blades may be driven by the tractor as the tractor' moves along over the field, and that it is not necessary to mate rially change the construction of the tractor. Furthermore, I employ the devices already provided upon the tractor for other purposes tor attaching my improved pulverizer and It will be understood that various changes in the detail of construction may be made without departing from the spirit or scope ot' the invention as defined by the appended claim. n

l claim:

In combination with a tractor, a transverse brace secured to the draw bar attaching means ot'y the tractor, brackets secured to the axle housing ofthe tractor and to said brace, supporting boxes for pulverizing de-v vices rigidly secured to said brace, a shaft journaled in said supporting boxes, and pulverizing devices mounted upon said shaft.

In testimony whereof I have signed my name to this speciiication.
